Title: Vapor growth device for semiconductor thin film
Inventor: IKEDA MASAKIYO
IPC: C30B25/14
Filed: 1985-07-11
Abstract: PURPOSE:To obtain the titled device capable of supplying a raw gas and a gaseous dopant, smoothly purging the gas remaining in the device and growing a uniform semiconductor thin film in the vapor phase by providing a main gas inlet tube and an auxiliary gas inlet tube of specified structure to the device. CONSTITUTION:A substrate crystal (a) is fixed on a susceptor 2 in a reaction tube 1, >=90% of a raw gas is introduced from a main inlet tube 3a and the substrate crystal (a) is heated to a specified temp. A doping gas, etc., is introduced from an auxiliary inlet tube 3b and a semiconductor thin film is formed on the substrate crystal (a). A gas blowoff pipe 8 with both ends closed and provided with plural small holes 9 on the side surface is fixed to the auxiliary inlet tube 3b in the shape of a T. The gas in the reaction tube 1 can be rapidly changed over, since the distance between the blowoff pipe 8 and the substrate crystal (a) is remarkably shortened. Consequently, the steepness of the grown semiconductor thin film against a doping profile and a hetero interface is improved. Besides, in the vapor-phase growth of a semiconductor thin film using a raw material causing an intermediate reaction, a uniform semiconductor thin film can be grown while controlling the intermedaite reaction.

Abstract: PURPOSE:To measure the density of radioactivity efficiently in a short time, by providing a sample concentrating device at the downstream of the sample collecting point, collecting the concentrated sample after the liquid having the density of ultralow radioactivity is concentrated above the limit to be detected and measuring the density of radioactivity. CONSTITUTION:Water for reprocessing 1 is collected in a sampling tank 2 and is stirred uniformly by using a pump 3 and a circulating line 4. At the time when the water comes to the uniform density, a valve 5 is opened and a liquid for sampling is put into a concentrating tank 6 and a circulating concentration is performed by a pump 7 and a reverse osmotic membrane 8. At this time, a concentration magnification is computed by a treating capacity of the reverse osmotic membrane 8, the treated time and an amount of the remaining liquid in the tank 6. When the water 1 is subjected to an about 100 times concentration, it is possible to measure directly by a radioactivity measuring device. By this way, when the processing water for radioactive waste liquid is made to pure water in order to reutilize in a nuclear power station, the density of radioactivity is measured efficiently in a short time.

IPC: E05F15/60
Filed: 1994-07-06
Abstract: PURPOSE:To manufacture a permanent magnet placed between an accelerating section and a braking section and used for a constant travelling section requiring no large thrust economically advantageously. CONSTITUTION:A plurality of permanent magnets are arrayed in two rows in the direction of the opening and closing of a door while holding a moving coil 2 mounted on the door. Rare earth magnets 3 having high magnetic flux density are used as an accelerating section A and a braking section B at both ends of the arrayed permanent magnets. Ferrite magnets 4 having low magnetic flux density are employed as a constant travelling section C between the accelerating section A and the braking section B. Since the permanent magnets used as the constant travelling section C between the accelerating section A and the braking section B do not require thrust larger than the permanent magnets employed as the accelerating section A and the braking section B, magnetic flux density may be lowered, thus resulting in economically advantageousness.

     CONSTITUTION: The powdered bodies dropping down through the inside of the inner bellows tube 17 collide with the surface of the pile of the powdered bodies A and cause the dust B. In this case, the generation of the dust is reduced by making the opening of the inner bellows tube 17 as much close to the surface of the pile of the bodies as possible. Thus, a level gage is fitted to a hood 18, the level of the piled powdered bodies A is detected thereby, and the inner and outer bellows tubes 16 and 17 are shrunk automatically by a wire 28. By this, the powdered bodies which drop down are made as much close to the surface of the pile of the powdered bodies as possible thereby to control the generation of the dust B. The dust B generated is sucked through between the outer and inner bellows tubes 16 and 17 by a blower and caught by the dust collector.
